Sinan Kaya 561e5d4896 RDMA/qedr: eliminate duplicate barriers on weakly-ordered archs
Code includes wmb() followed by writel() in multiple places. writel()
already has a barrier on some architectures like arm64.

This ends up CPU observing two barriers back to back before executing the
register write.

Since code already has an explicit barrier call, changing writel() to
writel_relaxed().
